M3 Zinc Plated Split Lock Washer/Conical/Spring Washer/ DIN127 B Stainless Steel 304/316

Standard split lock washers match with fasteners that have right-hand threads to prevent clockwise rotation. They have uneven split ends that bite into fasteners for a tight grip but won’t work with hardened surfaces. They hold better than curved or wave washers. These washers are not reusable after tightening.

Steel washers are stronger and resist wear better than zinc-plated steel and stainless steel washers. Use them in dry environments.
